介绍了一种球形水下机器人水声通信系统。通信系统将集成到多个SUR系统中，实现SUR之间的通信和多SUR系统的协作。该通信系统主要采用两种试验方法，即扩频跳频多址（FHMA）和正交相移键控码分多址（QPSK-CDMA）方法。通信模块采用Micron数据调制解调器。通信系统由信道编解码、扩频调制解调、通信模块对组成。实验结果表明，该系统具有较低的误码率，是实现水下通信的可行和可靠的方案。
This paper depicts an underwater acoustic communication system for Spherical Underwater Robots (SURs). The communication system will be integrated into the multiple SURs system to realize the communication between SURs and the cooperation of multi-SUR system. There are two main trial method adopted in this communication system, which are tamed spread spectrum and Frequency Hopping Multiple Access (FHMA) as well as Quadrature Phase Shift Keying-Code Division Multiple Access (QPSK-CDMA) method. The Micron Data Modem is employed as the communication module. The communication system consisted of channel encoding and decoding, spread spectrum modulation and demodulation, pairs of communication modules. The experiments results testify that the developed system is feasible and reliable to realize the underwater communication due to the low BER (Bit Error Ratio).
